背景和目的：虽然许多研究调查了因果模型对公众对精神病患者态度的影响，但因果模型对精神病患者的影响尚不清楚。因此，临床医生必须在不知道对患者和治疗有何影响的情况下决定是否提供因果信息。本研究探讨了因果模型对治疗动机不同方面的影响。方法：在一项实验性在线研究中，指示健康个体（n = 461）想象经历精神病症状并寻求专业帮助。想象是由一个音频播放的封面故事支持的。随后，参与者被随机分配到四种不同的条件下，这些条件对出现的症状给出了不同的因果模型（生物的、心理的、综合的和无因果解释）。结果：不同的因果模型影响治疗动机的不同方面：接受生物因果模型的参与者表现出高的服药意愿，而接受心理模型的参与者则表现出对症状的高感知个人控制。接受了结合生物学和心理学方面的因果模型的参与者报告了对药物的高接受度和接受该临床医生治疗的高动机。结论：结果强调了因果模型的内容可能对患者的治疗动机和治疗成功的影响。总的来说，就坚持各种类型的治疗而言，在因果模型中整合心理和生物学方面似乎最有希望。(C) 2011 Elsevier Ltd.版权所有。
Background and objectives: Although many studies have investigated the impact of causal models on public attitudes toward people with psychosis, the effect of causal models on patients with psychosis is unclear. Clinicians must therefore decide about providing causal information without knowing how it will impact on patient and treatment. This study investigates the effect of causal models on different aspects of treatment motivation.Methods: In an experimental online study healthy individuals (n = 461) were instructed to imagine experiencing psychotic symptoms and seeking professional help. The imagination was supported by an audio play cover story. Subsequently, participants were randomized to four conditions differing in the content of the causal model given for the occurring symptoms (biological, psychological, combined and no causal explanation).Results: Different causal models impacted on different aspects of treatment motivation: Participants who had received a biological causal model showed high willingness to take medication, whereas participants who had received a psychological model reported high perceived personal control over symptoms. Participants who had received a causal model that combined biological and psychological aspects reported high acceptance of medication and high motivation to undergo treatment by this clinician.Conclusions: The results underline the impact the content of a causal model may have on patients' treatment motivation and - as a consequence - on treatment success. Overall, the integration of psychological and biological aspects within a causal model seems most promising in terms of adherence to various types of treatment. (C) 2011 Elsevier Ltd.
